Led by Dr. Sean Darling-Hammond, Director, with support from Dr. Stephanie Guinosso, Lab Manager, the THESIS Lab conducts research to ascertain how K-12 school practices impact students’ sense of belonging, mental health, and wellbeing; and whether implementing particular practices might help enhance mental health and health equity. To reach this goal, THESIS conducts both qualitative and quantitative research with the aim of generating a body of evidence that can be used to impact the implementation of programs for youth in K-12 schools.
